Our oceans aren’t just rising - they’re accelerating, and that’s even worse

It's been hidden from us for 25 years.

On 15 June 1991, Earth sustained the second-largest volcanic eruption of the century - Mount Pinatubo, in the Philippines.

Described by the US Geological Survey as "cataclysmic", the eruption spewed forth more than 5 cubic km (1 cubic mile) of debris, and the resulting ash cloud rose some 35 km (22 miles) into the air above.

<...>

"The scientists estimate as a result that sea level not only fell between 5 and 7 millimetres due to a major ocean cooling event in the eruption’s wake, but then experienced a rebound, or bounce back, of the same magnitude once the influence of the eruption had passed," Chris Mooney reports for the The Washington Post.

This rebound made it look like sea levels experienced a sharp increase, followed by a decline, and then ultimately, it appeared to even itself out, but in reality, the results were completely distorted.

Thanks to the new, more accurate models of what’s actually been going on, we now have the first real evidence that global sea levels have been rising at an accelerating rate - something that scientists have been expecting, given the warming of our planet, but the records have said the opposite.

The last report I saw on the Lake Superior basin had rainfall in the southern and western parts of the basin falling by an inch per year, while the northern parts of the basin (aka Canada), rose by about an inch. Probably a net increase of water for Lake Superior due to the areas involved.

Rainfall in the Lake Michigan basis is usually modelled as falling due to climate change by about 2 inches which would lead to falling water level. I would have thought the flow of water out of Lake Superior would preclude Lake Superior rising multiple meters needed to flood the UP.

Surprising.
